I'm still fighting a rather irritating little bug so have a bit of time on my hands to check out the on-demand TV services of UK channels. I don't often switch over to Channel 5 as it's known as the home of the "When Celebrity Nazi Sharks Kill!!!" sort of program, but there were two watchable shows on Monday.
First up there was a "How do they do it?" about how they keep the Thames clean, by which they mean clean of rubbish. Its actually relatively unpolluted (for an urban river) and there are some 120 types of fish living in it.
But there is a lot of junk (above). So the rather hyper-active presenter Robert Lewellyn goes out on the aptly named Driftwood III (below), to pick up some of the 600 tonnes of waste in the river. On the river they took the rubbish out of the 9 passive driftwood collectors to dump in land fills.
They also went along to shore line at low tide picking up the non-floating rubbish such as one of the 250 shopping trollies found each year. Apparently they find about one car a month (some dumped and some "mis-parked") - once even an Aston Martin!
You should be able to watch it here - and also find out how they make bullet proof cars and Ikea makes and stores its flat pack furniture. The Thames bit is in the middle after about 7 minutes of bullet proof cars.
